To ALL WHOM Ir MAY ooNcEnN;

Be it knownl that I, BETHEL BURTON, of the city of Brooklyn, in the county of Kings, and State of New York, have invented a new and useful Improvement in Breech-Loading Fire-Arms; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, being r an improvement upon that for which Letters Patent were granted 'to me, December 20, 1859, reference being had to the annexed drawings, making partei' this specification, inwhichv Figure 1 is a. vertical section of vmy improved fire-arm atthe breech.

Figure 2 is a plan of the same, with the breech-pin drawn back.

Figure 3 is a cross-section of .the rear .end of breech.

AFigure 3 is a side elevation of the same, showing the bolt which lockstho breech-pin', with the bolt detached, upon which is shown the spiral spring, which keeps it in place. p l v Figure 4 iis a section of a. sliding cover, recoil-block, and steady-pim Figure 5 is across-section of the same.

Figure 6 is the breech-pin.

Figure 7 isa section ofthe hammer.

Figures 8 :md 9 are asecton end plnn of a. spring or cartridge-extra`ctor- I extend the barrel at by screwing thereon' a breech or cylinder, b. I form a. longitudinal slot or mortise' `into the cylinder, on the upper'side, from the point'b to and running under the ring c, formed on theupper side of cylinder, as` shown at cross-section, igS, c, to allow the slide e to move back and forward with the breech-pin f, without weakening the breech. Upon the forward'end of the .slide e there is a recoil-block,g,

and a steady-pin, z', running from said block, which enters the breech-pin f, when, by a partial rotation of theA sam'e, one portion or section o f the screw enters into o. recess in the under side fv the slide e, at o, and serves to connect them together, by which means the slide c and recoil-block gere carried back, with the breech-pin f, when withdrawn. On the under side ofthe slide c, a slot isv cut,`zis shown at y, in gs. 1, 4, and 5, in which the extractor g, figs. 8 and 9, works.

The slide or cover e is made. t'o extend entirely oler the extractor, to protectit from wet or kept in place by the breech-pin f, when, by a forward and turning motion of the breech-pin f, the sectional screws on said breech-pin enters a corresponding sectional screw in the rear of the chamber, substantially as set forth in my former patent,- and forces therecoil-block q, figs. 1 and 4,'ag'ainst 'the base orhead of the cartridge, which sustains the recoil. l

l'.ihe breech-pin f is bored out to within one-eighth ofan in ch of its base, -irn whichthe hammer and spiral spring m are made to fit, -and upon the trigger lc a finger, h, is pivoted, which passes up through thebreech and breech-pin, so that, when the breech-pin is withdrawn, the spring J upon the trigger-guard, pressing on a. ledge of the trigger k, keeps the iinger hpressed up in front of the hammer Z, holding .the hammer back,I while the breech-pin is pressed forward to close the breech, and, in so doing, the spring min the hammer lis compressed and ready for firing. The breech-pin f 'is prevented from turning, until the sectional screws are in position to beunited, by means of the finger k working in an I shaped slot in .the breech-pin f.

dirt, and isA To prevent n. premature discharge of the piccerbefore the breech-pin f is entirely screwed up, a slot is made, which forms a hook on the upper frontend of the finger k, as shown at 71, iig. 1, which hook passesvover the lip 1t on the rear of the slot in the breechpin f, fig. 6, so that the finger h cannot be pulled down until thebreech-pin f has been revolved o`r turned suiciently to bring the lip n from under the hook on the trigger', where an opening is cut, which allows` ofthe finger being drawn down by the action of the trigger. When the spiral spring is relieved, it forces Athe hummer forward against the head of thecartridge, bywhich means 'the fnlminate in tbe cortridgefi's ignited. l A

In order to carry the rm with'safety, when loaded, it is only necessary to turn the breech-pin until the lip n is brought under the'hook on the ng'er h, when it i's secured, se that the arm can-not bedisoharged.

To hold the breech in this position, I employ a bolt on the breech, as shoivn at figs. 3 and 3l, running 4into a hole in the lever, to prevent the breech-pin ffroni turning. In ordervto withdraw the breech-pin nndsliding cover entirely out, the Ihook on the finger h must be drawn down below the breech-pin which `allons olf their free passage in and out of the chamber of th'c breech in which they werk. f

In order to expel the shell of the cartridge from thel chamber of the breech, whcnfwlithdramvn. from the barrel, a projection, c, on thc under side of the recoil-bleek, gs. 4 and 5 supports the' rim of the cartridge, and prevents its dropping down from the hook et'Y the extractor, until itl clears the end of the barrel4 when lthe pressure exerted by the spring m on the pin 'p against the cartridge, tilts itnp andout ofthe chamber of the What I cla-im as my invention, and desire to secure by Letters Patent, is. 4

1. The construction of the breech or cylinder, withthc opening for the slide e to pass under the ring c, by lwhich means the yopening is entirely 'closed from access of 'sand r dix-t., when thebrelcc'h is eloscgl. i

2. The recoil-'block g, stecdy-pin z', and slide Vcombine-ci with the breeehgpin f and sectional screws or cam, which enters the recess `at c, lfor combining 4or coupling the enmewithont thc use of a. screw or other fastening. i I

3. The manner of combini with screws or other fastenings.

4. The combination and arrangement of the springthe same motion the said breech is opened to receive n eartridgc a the chamber by thc pressure of the hammer, substantiallyV as `set forth.

5. The hook-ended finger h upon the trigger the slot and lip in breech-.pin f, the safety-bolt, iig. 31, for

keeping the breech-pin locked, and as sct forth. A

ng the extractor q with the slide e by means of the slot or recess y, dispensing hammer l with the lsliding breech, Vso that by one and nd the empty cartridge-shell ejected from BETHEL BURTON.
